Final answer:
A formal problem-solving model is a systematic approach that helps people solve problems in a logical manner and involves different stages such as strategy, execution, and evaluation.
Step-by-step explanation:
The question regarding problem-solving models is related to the strategies used to approach and solve different kinds of problems, often found within the context of physics education. Specifically, the answer to the question is (d) helps people solve problems in a logical manner. While problem-solving steps can vary in number, they often include the following general procedures: identifying the problem, devising a strategy, executing a solution, and evaluating the significance of the solution. This method applies systematic problem-solving strategies such as identifying knowns and unknowns and using analysis and evaluation. The process is designed to be logical and can involve creativity and insight. It is essential not only in the academic setting but also for real-life applications where analytical skills are required.
Problem-solving is a form of knowledge that goes beyond memorizing facts, as it involves applying analytical skills and problem-solving abilities to new situations, useful in everyday and professional life. It's important to recognize that a problem-solving model can be applied to a wide range of scenarios, from complex equations to practical issues like fixing a broken printer.
